It's most likely a flashback sequence that they filmed. It at the very least confirms her cameo. I'm assuming it has something to do with Logan remembering his past and why he's gone to Japan in the first place to seek solace, and find a new purpose after the events of "The Last Stand".

Wasn't there some photos of Wolvie with bone claws circulating around?? I wonder if he gets the andamantium ripped out of his body?!?! The new 20 second trailer kinda sounds like that's what they were saying at the end of it... Am I tripping?? lol

I'm still not sold on this movie. They had a couple of cool posters earlier on but all the footage so far just looks like Elektra or something. Hopefully the actual trailer will clue us in to the actual story as opposed to action shit flying around everywhere.
